Getting Information From A Control Added At Runtime

[coldfusion244]

Hello again!

 

I am in a quandry. I have a tabcontrol, on which I create a few controls. One of those controls is a textbox, for use to input a string of data. The problem I am having is that of getting the data from it. The code i'm using is:

	//create new tabpage, name it and label it
	TabPage tbtemp = new TabPage("Report: " + strtemp[2]);
	tbtemp.Name = strtemp[5];

	clsReports MyReports = new clsReports();
	//create a new report
	MyReports.iReportNumber = int.Parse(strtemp[5]);			MyReports.strServerIP = strtemp[1];
	MyReports.strPlayerName = strtemp[2];
	MyReports.strReason = strtemp[3];
	MyReports.strExtra = strtemp[4];
			
	AllReports.Add(MyReports);
	tbReports.TabPages.Add(tbtemp);
	//start adding runtime controls
	Label lblServer = new Label();
	Label lblPlayer = new Label();
	Label lblReason = new Label();
	Label lblTime = new Label();
	TextBox txtPass = new TextBox();
	//start setting the labels values
	lblServer.Name = "lblServer" + strtemp[5];
	lblServer.Text = "Server: " + strtemp[1];
	lblServer.Location = new Point(10,16);
	lblServer.AutoSize = true;
	
	lblPlayer.Name = "lblPlayer" + strtemp[5];
	lblPlayer.Text = "Player: " + strtemp[2];
	lblPlayer.Location = new Point(10,48);
	lblPlayer.AutoSize = true;

	lblReason.Name = "lblReason" + strtemp[5];
	lblReason.Text = "Reason: " + strtemp[3];			             lblReason.Location = new Point(10,80);
	lblReason.AutoSize = true;

	lblTime.Name = "lblTime" + strtemp[5];
	lblTime.Text = " Submitted: " + strtemp[4];
	lblTime.Location = new Point(7, 112);
	lblTime.AutoSize = true;

	txtPass.Name = "txtPass" + strtemp[5];
	txtPass.Text = string.Empty;
	txtPass.Location = new Point(10,144);


	//add controls to the tabpage
	tbtemp.Controls.Add(lblServer);
	tbtemp.Controls.Add(lblPlayer);
	tbtemp.Controls.Add(lblReason);
	tbtemp.Controls.Add(lblTime);
	tbtemp.Controls.Add(txtPass);
	//finally show the controls
	lblServer.Show();
	lblReason.Show();
	lblPlayer.Show();
	lblTime.Show();
	txtPass.Show();

 

It's probably an easy solution, I googled for it but didn't find any answers for .NET. :(

 

Thanks guys!

Show the code where you are trying to get the data from the control. Is should be simple once you know the name you have given the control.

I know the name of the control, it would be

"txtPass" + creport.iReportNumber;

 

The problem I am having is how access it's data. Do I access it just like it was always there?

You should be able to use something like

 

Dim str1 As String

str1 = tbtemp.Controls(txtPass & creport.iReportNumber).Text

You should be able to use something like

 

Dim str1 As String

str1 = tbtemp.Controls(txtPass & creport.iReportNumber).Text

 

That doesn't work... I get a compiler error.

 

--EDIT--

 

Ok, figured out how to do it. This is probably the worst way possible to do it, so if you know a better way PLEASE tell me!

 

Since there is only 1 textbox on each new tabpage I create I used the following:

string b = string.Empty;

foreach(Control a in tbselected.Controls)
{
if(a.GetType().ToString() == "System.Windows.Forms.TextBox")
{
	b = a.Text;
}
}

 

Glad I don't have many controls, or that would create some serious performance issues!

At the very least you could get rid of the ToString and the associated string comparison by doing

if(a is System.Windows.Forms.TextBox)
{
b = a.Text;
}

for the check
